LOCKING MEANS FOR DOORS.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed August 28, 1914. Serial No. 859,015.

To all whom it may concern:

Be it known that I, JAMES SHIREY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Lock ing Means for Doors, of which thefollowing is a specification.

My invention relates to improvements in locking-means for doors, and myobject is in general to provide a simple, strong and durablelocking-mechanism capable of application to all common forms of doors.

Further objects and advantages of my invention will appear'from thefollowing detailed description of the same, in which, for purposes ofillustration, I will particularly describe an embodiment of theinvention as applied to a well-known type ofdouble-door.

In the description, reference will be made to the accompanying drawings,in which Figure 1 is a front elevation of a double door and frame forthe same, showing the locked and unlocked positions; Fig. 2 is adetailed perspective view of the slide-rod and the connection with thelockin -bar; Fig. 3 is an enlarged sectional view of the end of thelocking-bar and the socket of the doorframe in which it engages; Fig. 4:is a section on line 4 of Fig. 3; Fig. 5 is an enlarged front elevationof the locking-platewhich is secured to the door, the key of thelockingbar being shown in section; Fig. 6 is a section on line 6 of Fig.5, showing also the locking-bar and key; Fig. 7 is a rear face view ofthe locking-plate; Fig. 8 is a section on the line 8 of Fig. 6, and Fig.9 is a detail section on the line 9 of Fig. 1. a

In the drawings, 10 indicates the doorframe in which is mounted a pairof swinging-doors 11, 12. These doors may be of either of the one-way ortwo-way type, the locking-means being adapted for both constructions, aswill later appear. To apply my lock to such a door and frame, I mountupon the inner face of one of the vertical frame-members a slide-bar 13which is spaced away from the door-frame, as by the angular feet 14.Mounted to slide on the bar'13 is a sleeve 15 which has formed thereonthe tongue 16 to which is pivoted, as by a pin or rivet 17 ,theslotted-end plug 18. The outer end of the plug is reduced as at 19 tofit within the bore of a ingly flared surfaces tubular locking-bar 20, i

a bolt or other fastening means, indicated at 21, being employed to holdthe plug within the bore of the tube. Intermediate the length of thelocking-bar it is encircled by split sleeves 22 carrying key-members 23which are adapted to engage within the key-holesha'ped apertures oflocking-plates 24. The split sleeves 22 are clamped in proper positionupon the locking-bar by cap-screws 25.

Referring to Figs. 5 to 8, it will be seen that the locking-plates 24are let into the face ofthe door, as indicated at 26, so as to lie flushwith the same, and are secured in position, as by counter-sunk screws27. Back of the plates the doors are cut away to form rectangularrecesses 28 which accommodate the enlarged ends 29 of the keys. Theapertures 30 of the locking-plates are of key-hole shape, as stated, sothat the enlarged ends of the keys may be introduced into the upperenlargement of the apertures 30, and upon being moved downwardly arelocked within the recess 28 by the side walls 31 of the lower narrowedends of the apertures 30. As shown in Fig. 8, these sidewalls flareinwardly to engage correspond- 32 on the enlargements 29 of the keys. Asa means of drawing the sleeves 22 tightly into engagement with the outerfaces of the locking-plates, I form upon the inner faces of thelocking-plates the inclined surfaces indicated at 33 in Fig. 6. Thesesurfaces co-act with the enlarged heads 29 of the keys, to wedge thesame tightly in place as the keys are forced clownwardly in the slots.

Referring to Figs. 3 and 4, it will be seen that the free end of thelocking-bar is slotted at 33 to receive a hasp 3% which is threaded intothe telescoping tube-section 35. A second hasp, shown at 36, is threadedinto the wall of the locking-bar so as to lie adjacent to and inalinement with the hasp 34 when the telescoping-section 35 is in itsextended position. To look the hasps in the position shown in Fig. 3, apadlock, conventionally illustrated at 37 may be employed. Thetelescoping-section 35 engages within a socket 38 let into the innerface of the vertical side-frame member of the door-frame. This socket,like the locking-plate, is preferably flush with the surface in order topresent a neat appearance. A socket 39, similar to the socket 38, may belet into the under face of the top-frame member of the doorframe. 1

The operation of my locking-mechanism is as follows: When the parts arein the unlocked or inoperative position, as indicated.

in dotted lines in Fig. 1, the telescopingsection 35 will be engagedwith the socket 39, (being so held by the padlock 37, not shown in thisfigure) the sleeve 15 will be at the bottom of the slide-bar 13, and inthis position of the parts the doors will be entirely unobstructed andfree to swing in either direction. When it is desired to lock the doors,.the padlock 37 will be removed and V .-;imately horizontal positionopposite the locking-plates of the doors, the keys 23 being opposite theenlarged upper ends of the apertures in the locking-plates. The free endof the locking-bar which formerly stood at a slight angle to the doorswill now be moved back toward the same, causing the keys 23 to passthrough the apertures in the locking-plates, and when this has beeneffected, the free end of the bar will be swung --downwardly, thuscausing the keys to move downwardly and become wedged within the lowerslots of the locking-plates. If the parts have been accurately fitted,the end of the locking-bar will now stand opposite the socket 38, andthe hasp 34 may be pushed forward to engage the telescoping-section 35within the socket. The padlock 37 may then be snapped through the hasps34, 36. It will be seen that in this position of the parts the doors arepositively held against all movement. If they are folding-doors, asdescribed, they can not be swung in either direction, the keys 23 beingwedged so tightly Within the apertures of the locking-plates as to evenprevent rattling of the doors. As an additional means of preventingrattling of the doors, I may fasten to the faces of the same the wedgeplates 40, shown in Figs. 1 and 9. These plates have inclined frontfaces which in the locked position of theparts bear against and tightlywedge the locking-bar 20. These plates 40 are not at all necessary tothe action of the locking means, however, and need only be used where itis important to prevent the least rattling of the parts.

It will be readily understood that the form of locking-means which Ihave described as applied to a double swinging-door will serve withoutchange for a single door of the swinging type or for a single or doubledoor of the sliding type, the form of the locking arrangement being suchthat the door or doors are positively held against all movement. Thesame form of locking device may be applied in precisely the same way torevolving-doors, it being understood that the sections ofrevolving-doors are pivoted to one another so that they may be broughtinto a single plane when it is desired to lock the door. In suchposition of the parts, the door-sections would occupy the same relationto one another as do the. double folding-y doors 11 and 12 in Fig. 1,and the locking bar'would be applied'in precisely the same way,excepting that it would be necessary, of course, to recess thedoor-frame or casing to receive the slide-bar 16 and also to receive thelocking-bar when it is in the inoperative position. Y Y

In order to'adapt my locking mechanism for doors of different sizes, itis'only necessary to change the length of the locking-bar i and theslide-bar, andthis maybe done by any dealer in such apparatus. Thelocking? plates and all other fittings are identically the same for allclasses and sizes of doors to which the locking-mechanism may beapplied.

\Vhile I have shown and described in considerable detail a constructionembodying my invention, it is to be understood that such description andshowing is illustrative only, and that my invention is not to beconstrued as limited to the structural features or combinations ofelements shown, except in so far as such limitation is included withinthe appended'claims.
